The memory fitness program: cognitive effects of a healthy aging intervention.

CONTEXT: Age-related memory decline affects a large proportion of older adults. Cognitive training, physical exercise, and other lifestyle habits may help to minimize self-perception of memory loss and a decline in objective memory performance. OBJECTIVE: The purpose of this study was to determine whether a 6-week educational program on memory training, physical activity, stress reduction, and healthy diet led to improved memory performance in older adults. DESIGN: A convenience sample of 115 participants (mean age: 80.9 [SD: 6.0 years]) was recruited from two continuing care retirement communities. The intervention consisted of 60-minute classes held twice weekly with 15-20 participants per class. Testing of both objective and subjective cognitive performance occurred at baseline, preintervention, and postintervention. Objective cognitive measures evaluated changes in five domains: immediate verbal memory, delayed verbal memory, retention of verbal information, memory recognition, and verbal fluency. A standardized metamemory instrument assessed four domains of memory self-awareness: frequency and severity of forgetting, retrospective functioning, and mnemonics use. RESULTS: The intervention program resulted in significant improvements on objective measures of memory, including recognition of word pairs (t([114]) = 3.62, p <0.001) and retention of verbal information from list learning (t([114]) = 2.98, p <0.01). No improvement was found for verbal fluency. Regarding subjective memory measures, the retrospective functioning score increased significantly following the intervention (t([114]) = 4.54, p <0.0001), indicating perception of a better memory. CONCLUSIONS: These findings indicate that a 6-week healthy lifestyle program can improve both encoding and recalling of new verbal information, as well as self-perception of memory ability in older adults residing in continuing care retirement communities.

Enhancing older driver safety: A driving survey and evaluation of the CarFit program.

OBJECTIVE: To evaluate CarFit, an educational program designed to promote optimal alignment of driver with vehicle. METHODS: A driving activity survey was sent to 727 randomly selected participants living in retirement communities. Drivers (n=195) were assigned randomly to CarFit intervention (n=83, M age=78.1) or Comparison (n=112, M age=79.6) groups. After 6months, participants completed a post-test of driving activity and CarFit recommendations. RESULTS: Nonconsenting drivers were older and participated in fewer driving activities. CarFit participation was moderate (71%) with 86% of the participants receiving recommendations. 60% followed the recommendations at the 6-month re-evaluation). The CarFit (67.6%) and Comparison (59.3%) groups reported at least one type of self-regulation of driving activity at baseline. There was no significant change in the driving behaviors at the six-month follow-up. CONCLUSION: CarFit was able to detect addressable opportunities that may contribute to the safety of older drivers. IMPACT ON INDUSTRY: CarFit recommendations may need stronger reinforcement in order to be enacted by a participant.
